SPECIFICATION forming part of Letters Patent No. 552,431, dated December31, 1895.

Application filed March 18, 1895. Serial No. 542,237. (No modeLl To allwhom, it may concern:

Be it known that l, ADRIAN GAJARDO, engineer, a citizen of the Republicof Chile, residing at 1b Calle Prat, Valparaiso, Chile, have inventedcertain new and useful improvements in automatic apparatus forregistering the number of passengers in railway and other vehicles, andalso the number of persons entering or leaving buildings or the like, ofwhich the following is a specification, reference being had to theaccompanying drawings.

My invention relates to improvements in auton'iatic apparatus forregistering the nu n1- ber of passengers in railway and other vehicles,and also the number of persons entering and leaving buildings or thelike.

The object of my said invention is to provide improved apparatus for.registering exactly and exhibiting a visible enumeration of the numberof persons traveling, say, in tram-cars, omnibuses, or other vehicles,steamboats, and the like, to which the apparatus is applied, or thenumber of visitors enterin g or leaving exhibitions, parks, theaters,museums, and other places of public resort. The aforesaid improvedapparatus also automatically duplicates the count and therebyeffectively prevents any fraudulent attempt on the part of the employsor officials intrusted with the collection of the admission fees, orfares, to deceive their employers by reportin a less number of visitorsor passengers than have really been admitted to the establishment, orcarried by the conveyance, in question.

An important feature of this apparatus is that, while it automaticallycounts and registers every individual passenger or visitor who passesthrough it in either direction, it comprises improved means for allowingthe conductor, or other authorized attendant, (furnished with suitablesole-plates on his boots,) to pass through without being counted orregistered. Such attendant or official cannot,

however, substitute any one else in hisplace, unless that person is inpossession of the means for preventing the counting or registeringdevice from operating in his case.

Another feature of the invention is the pro vision of improved means fornotifying or announcing the passage of an authorized employ, whenever itoccurs, by the sound of a bell, trumpet, or other signaling device.

The improvements herein described may be classified under three heads,viz: First, the improvements in the construction of the doors, gates, orturnstiles, which, as is usual in such apparatus, are opened to let onlyone person through at one time; second, the improved devices operated bythe door or gate for counting the number of people passing through andimproved means for throwing the counting device out of action when theattendant is passing through the gates, and, third, the improved deviceelectrically connected with the counting device directly operated by thedoors or gates and operative to reproduce at a central office or otherplace at a distance from said doors or gates the number which isregistered by such counting device.

In the accompanying drawings, Figure 1 is a front view, and Fig. 2 is aplan, of a pair of entrance-gates constructed according to my invention,the gates being closed. Fig. a section on line 3 3, Fig. 1. Fig. 4 is aplan showing the gates partly open. Figs. 5 to 8 are detail views drawnto alarger scale of one of the hinges of the gates hereinafter fullydescribed. Fig. 9 is an under plan view sl1owing a device for connectingtogether the shafts of a pair of gates. Fig. 10 is a similar viewshowing an alternative form of such device intended for rotating gatesor turnstiles. Fig. 11 is an elevation of my improved counting device.Fig. 12 is an elevation of my improved electrically actuated duplicatingregister. Fig. 13 is a section of the shaft 0 shown in Fig. 11, showingthe cam thereon for operating the counting device. Fig. 1a is a sectionthrough the wheels of the counting device. Fig. 15 illustrates amodified counting device with the upper registering-wheel removed toshow a pawl hereinafter described. Fig. 10 is an under side plan of thesaid upper registering-wheel.

Referring now to Figs. 1. to S, A A is the framework forming the sidesof the passage through which the people pass. 1-3 B are the gatessecured to upright shafts C O. D D D D are auxiliary gates mounted onthe shafts O O and capable of rotating thereon. The shafts O C areturned when the gates B B are opened and actuate the counting orregisterin g device, as herein after described. The pur pose of theauxiliary gates is to close the passage immediately in rear of theperson passin g through the same as soon as the gates B B are opened.

For the sake of clearness I will describe the construction and operationof one gate B only, premising that the other gate is constructed andoperated in the same manner.

The shaft C is supported at the top in a bearing C (see Fig. in theframe A and at the bottom is pointed and supported on an adjlisting-screw C secured in a suitable foun dation-plate. (Clearly shownin Fig. 3.)

The manner of mounting the gates D D 011 the shaft is shown in Figs. 5to 8, where Fig. 5 is an elevation of the hinge looking in a directionparallel with the gate B, Fig. (3 is an elevation looking in a directionparallel with the gates D D, Fig. 7 is a section on the line 7 7, Fig.5, and Fig. 8 is a section on the line 8 8, Fig. 5. The figuresillustrate the lowermost limbs of the gates. E is a collar firmlysecured to the shaft 0 by a screwed pin E. (See Figs. 7 and 8.) To it isattached the lower horizontal arm of the gate B. The said collar isslotted, as shown at E to receive two rings F F, which are adapted toturn easily on the shaft C, and to which rings the horizontal arms ofthe gates D D are respectivelyfastenedthat is to say, one of the saidgates D is secured to the upper ring F and the other of said gates D issecured to the lower ring F. The said rings F F are hollow or U-shapedin section, as shown in Fig. 8, and are so placed relatively to eachother that an annular chamber is thereby formed. In this chamber isplaced a helical spring G, one end of which is secured by a stud G toone of the rings and the other of which is secured by a stud G to theother ring. Other suitable means for securing the ends of the spring maybe adopted. The spring is so arranged that it tends to main tain boththe auxiliary gates D D pressed against the wall A (see Fig. thatextends across the frame A.

F F are projections or stops secured to the rings F F, respectively, andadapted to be received in notches D D in the auxiliary gates D D whenthe said rings are turned. The gates D D cannot turn through more than aright angle or thereabout since the projection F or F as the case maybe, will at the end of that amount of rotation come into contact withthe end of the notch D or D in the other auxiliary gate which is bearingagainst the wall A or against a simple bar extending across the frame.The said wall or bar is furnished with rubber or leather or othersuitable buffers to receive the shock when the auxiliary gates D Dstrike thereagainst.

The operation of the gates is as follows that is to say: When the gatesB are opened, in the direction shown, for example, in Fig.

7, the part E Fig. 7, of the collar E of each gate pressing on thecorrespondingauxiliary gate D causes the latter to turn and follow thesame course as the gate B, and, finally, when the gate B is fully opento take up the same position as that which the said gate B occupiedbefore being opened. The other auxiliary gate D meanwhile remains atrest against the wall A. If the gate B is opened in the oppositedirection, the auxiliary gate D is moved in a similar manner to closethe opening and the gate D remains stationary Therefore immediately thegate B is turned to open the passage, the gate 1) or gate D moves out toclose the passage. This arrangement prevents more than one'personpassing at a time, since either one or the other of the auxiliary gatesmust impede the passage of a second person at the moment when the gate Bis open to afford a free passage for the first person. The gate D inturning with its ring F upon the shaft 0 while the other gate 1) is atrest will distort the spring G in such a manner that as soon as the gateB is released the spring will act to return the gate D and with it thegate B to its initial position. \Vhen the gate B is opened in theopposite direction the gate D operates to distort the spring and is inturn forced back by the spring when the gate B is released.

I prefer to provide two gates B B and two sets of auxiliary gates D andD, as shown in Figs. 1, 2, and 4, and in this case, in order to insurethat when one of the gates B is opened the other shall also be opened, Icouple them together by crank-arms O 0 secured to the shafts C C, asshown in Figs. 3 and f), and a link II.

Referring now to Fig. 11, I will proceed to describe the counting devicewhich is actuated when one of the shafts U is turned or partly rotatedby the opening of the gate B. The counting device comprises two dials L,mounted in a suitable casing Y carried by the frame A. One of the saiddials L counts the number of persons admitted or, in other words, thenumber of times the entrance-gate and shaft C are rotated through arightangle or thereabout in one direction, and the other of which counts thenumber of persons passing out or, in other words, the number of timesthe entrance-gate and shaft 0 are rotated through a right angle orthereabout in the other direction. The shaft 0 is provided with acam-piece C having two faces 0 C, (see Fig. 13,) one of which G" acts onthe bar or red K of the admission counting device, and the other G actson the corresponding bar or red K of the exit counting device. The twocounting devices are similar in their construction and action, so thatthe description of the device that counts the number of admissionswillapply also to the exit counter.

The rod K is mounted to slide in suitable guides 76 and is pressedagainst the cam-piece C by a spring K K is a spring-pawl carried by therod K and adapted to engage with a ratchet-wheel L, as shown. The saidratchet-wheel L is provided with a suitable number of teeth one hundred,for example and is graduated on its upper flat face.

L is astationary pointer which registers from 1 to 100. Below the wheelL is another toothed wheel M", (see Fig. 14,) having, say, one hundredand one teeth. Its boss projects through the center of the wheel L andis furnished with a pointer M to register hundreds on an inner graduatedcircle on the upper face of the wheel L. The pawl K engages with theteeth of both wheels L M and rotates them simultaneously. Since,however, the wheel M has one tooth more than the wheel L it follows thatwhen the latter wheel has completed one rotation the wheel M will be atooth short of completing its rotation, and hence the pointer M willhave traveled one division over the scale on the disk L and willregister one hundred thereon.

The operation of the apparatus is as fol lowsthat is to say, when thegate B is pushed open to admit a person the shaft 0 is rotated through aright angle or thereabout and the cam-face C say, slides the rod K inits bearings against the force of the spring K thus causing the pawl Kto turn the wheels L M one tooth forward, and thereby registering oneunit. When the gateB closes, the camfaee recedes from the rod K and thelatter is returned to its initial position by the spring K A suitablespring-pawl L prevents the backward rotation of the wheel L when thepawl K is drawn back over the ratchet-teeth by the return of the rod K.If the gates B be moved in the opposite direction the camface operatesto move the rod K, which controls the other register, and thus thenumber of persons passing out are registered. In some instances, insteadof applying the register direct to the shaft C, I place it some distanceaway from the gates-on a wall, for exampleand operate it by a shaft I,Figs. 0 and 15, on whichisfixeda crank I, Fig. 9, connected bya link IIwith one of the cranks O Hy improved device for permitting the conductoror other official to pass through the gates without being registered isshown in Figs. L and 11.

N N are electromagnets which are energized when a current flows in thecircuit 01 n n 7L3. The said circuit includes a suitable battery B andterminates in two insulated comb-shaped bars N N between which extendthe teeth of another insulated comb-shaped bar N (See Fig. at.) The saidbars N N N 3 form a footplate. The armatures of the said electromagnetsare formed by the rod K carrying the spring-pawls K.

The gate-keeper or other o'l'l'icial who should be able to pass throughthe gates without affecting the registering apparatus has metallicplates fixed on the soles of his boots, and when he steps with both'feet on the plates N N in passing the gates the circuit 71 n n 71 iscompleted. The magnets N N then become energized and attract theirrespective armatures, whereupon the pawls K are withdrawn from theirratchet-wheels. Hence, although the gate is moved and the shaft 0rotated, neither of the ratchet-wheels is operated and themarking-pointers L and M do not move.

It is necessary for the gate-keeper to place both feet on thefoot-plate, as there are two gaps in the circuitviz., the gap betweenthe plates N and N and that between the plates N and N both of whichmust be simultaneously bridged over to complete the circuit. Hence itwill not be possible for the attendants to pass any friend throughwithout affecting the register, because when he has both feet inposition to complete the circuit his body will entirely block thepassage through the gates. At the same time the steppingplates are soconveniently placed that the attendant cannot fail to withdraw theoperatin gpawls before opening the gate.

I will now describe the arrangem ents which I provide for marking at adistant place the number of persons passing through the gates.

Referring now to Fig. 12, O O are ratchet- Wheels having graduated disksand pointers and other toothed wheels underneath, arranged in the samemanner as the ratchetwheels L lWI hereinabove described. P P are rodsmounted between rollers 19 p and provided with spring-pawls O 0 adaptedto engage with the ratchet-wheels O O. The rods P P are pressed towardeach other by pivoted L-shaped levers P P furnished with adjustableweights P P, as shown. 0 0 are spring-pawls which prevent a returnmovement of the ratchet-wheels. The rods P P are separated bya pendulumQ, which constitutes the armature for the electromagnets R- R. The coilsof the said electromagnets are united at r and joined to earth.

1", Fig. 11, is a Wire joined to two springs S S on opposite sides ofthe shaft 0. The said springs are furnished with projections or pawls SS which engage with the teeth of the ratchet-wheels of the countingdevice, so that when the wheel L, for example, turns the spring S ispushed away from the wheel and caused to make contact with a point S,from which a wire is led to the second terminal 0, Fig. 12, of theelectromagnet R of the distant counting device and closes the circuit ofthe said electromagnet, whereupon the said magnet is energized by thebattery contained in its circuit. The spring S operates in a similarmanner to close the circuit of the other electromagnet R of the distantcounting device during the movement of the other ratchetwheel of thecounting device at the gate. Therefore when any person is admitted atthe gate and the ratchet-wheel L is operated, the circuit of theelectromagnet R is closed by the spring S. The pendulum Q is thenattracted by the electromagnct R and is thus drawn aside and caused toslide the rod P between its rollers 29. This movement of the rodoperates through the pawl O and causes the wheel 0 to turn one divisionfarther and thus register another admission. As soon as the movement ofthe wheel L is completed the spring S breaks the circuit of the electromagnet R. In a similar manner when the other wheel of the countingdevice moves during the exit of any person, the circuit of theelectromagnet R is closed and the pendulum Q is attracted with theultimate effect of moving the wheel 0, which thereupon registers adeparture.

The battery B is connected to the wire r, Fig. 11, which wire is commonto the circuits of both electromagnets R R. The springs S S areelectrically connected together in any suitable manner.

I prefer to place an electric bell or other signaling device in thecircuit that is closed by the attendant when he steps on the footplate NN N between the gates, so as to afford an audible indication of the factthat the attendant is passing through. The same signal would be givenwere any unauthorized person to succeed in passing through withouteffecting the register, and by this means the attendant would benotified of the fact in time to rectify the mistake or stop the intruder.

In some instances a separate signaling-circuit is provided, which isclosed by the movement of the spring-pawl K, when the latter is drawnback by its electromagnet.

It will be readily observed from the foregoing description that theduplicate register at the central or distant office is operated onlywhen the counting device at the gate operates.

The aforesaid duplicate registering device may be placed at any station,however distant from the gates, and will operate as a check on theinstrument at the gates. It will also serve to show the manager orproprietor, for example, how many people are passing through the gatesat any time.

I sometimes modify the counting device so that the wheel which registersthe hundreds is moved only when the hundredth person passes through thegates. This modification is shown in Figs. 15 and 16. I11 this instancethe driving-pawl K does not engage with the lower wheel M, but only withthe upper or units wheel L. The latter wheelis furnished with a projection Q on its lower face, which projection passes once each rotationof the wheel under a latch Q, pivoted at Q and raises the said latchagainst the pressureof its spring Q. As soon as the projection haspassed from under the hooked end of the latch the latter is forcedinward again by its spring. To the latch Qis pivoted apawl Q", thatengages with the teeth of the wheel M, being maintained in engagementbya spring Q \Vhen the latch Q is raised, as aforesaid,

by the projection Q it carries the pawl Q back over one tooth of thewheel M, and then when the latch Q is released and forced inward by itsspring the pawl Q operates to turn the wheel M through one tooth andthereby registers one hundred more on the dial.

The shaft I, Fig. 15, is connected with and controlled by the shaft 0 ofthe gate, said shaft G having affixed thereon a crank C to which ispivotally connected one end of a link II, the other end of which is inlike manner connected to a crank I,rigidly mounted on the shaft I.

To cause the turnstiles to move in unison the shafts O are connectedtogether by a link H. (SeeFig. 10.) The link II is pivotally connectedto the cranks C rigidly mounted on the shafts C, and midway between itsends is slotted, as at 11*, and fitted over a pin J fixed in the base ofthe apparatus. The pin J acts as a fulcrum upon which the link works,and the slot H permits of the longitudinal movement of the link.

By myinvention I effect a saving of capital or Working expenses byenabling the staff of officials or attendants employed in issuing andcollecting tickets or checks and receiving the entrance fees or fares tobe reduced, and that class of officials who have been hitherto appointedto examine, check, and countersign tickets, and who are generally calledinspectors, to be altogether dispensed with; and a further saving willresult from the fact that this device enables the proprietor ormanagement to avoid the necessity of providing at a considerable costspecial checks or slips for the prevention of fraud.

My invention is also particularly adapted to operate in connection withelectrical railways, wherein the current is sent through conductingwires and coils, as the means for operating the counting device, inaddition to registering the number of travelers in the vehicle itself,can, as hereinabove described, simultaneously make the same duplicateenumeration at some permanent offi ce or station electrically connectedwith the vehicle or car. The number of persons who have entered the carup to any given moment, and of those who have alighted and consequentlyof those who are still traveling at the time under consideration, may betherefore readily ascertained at the station, office, or place where theduplicate device is stationed. The device may also be used atexhibitions, thea ters, and other similar establishments, so that apermanent record is kept at the station or counting-house as well as atthe gates of all the persons who have entered and left, and of those whostill remain in the building or establishment in question.

I claim- I. The combination of a gate 1 carried by a shaft 0, auxiliarygates I), I) mounted on the said shaft, rings 1*, I to which theauxiliary gates are attached and a spring G connecting said ringstogether and operating to turn them in opposite directions,substantially as described;
